Lithium–silicon batteries are lithium-ion batteries that employ a silicon-based anode, and lithium ions as the charge carriers. [1] Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon. [2] The standard anode material graphite is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC 6.
Overall, the improved performance of Si-based anode materials has been attributed to unique structural designs and the excellent properties of the carbon materials. Several literature reviews have explored the development of Si/C composite anode materials for Li-ion batteries from different perspectives.
Silicon-based anodes for lithium-ion batteries have been the subject of extensive research efforts due to the fact that their theoretical gravimetric capacity surpasses that of graphite by ten times. 1–5 However, the considerable volume change upon lithiation and delithiation introduces significant constraints on the materials design.
